Chapter 1 What Are ControlLogix Digital I/O Modules?
I/O Modules in the
ControlLogix System
ControlLogix modules mount in a ControlLogix chassis and require either a
removable terminal block (RTB) or a Bulletin 1492 wiring interface module
(IFM)
(1)
to connect all field-side wiring.
Before you install and use your module, you must do the following:
• Install and ground a 1756 chassis and power supply. To install these
products, refer to the publications listed in Additional Resources
on
page 12.
• Order and receive an RTB or IFM and its components for your
application.
(1) The ControlLogix system has been agency certified using only the ControlLogix RTB catalog numbers 1756-TBCH, 1756-TBNH,
1756-TBSH, and 1756-TBS6H. Any application that requires agency certification of the ControlLogix system using other wiring
termination methods may require application-specific approval by the certifying agency.
RTBs and IFMs are not included with your module purchase. See page 116 for
RTBs and page 239
for IFMs.
